Redraw Limit
With some complex scenes, you may be unable to move objects smoothly in the viewports with full
shading due to hardware limitations such as processor speed. To help resolve this issue, CINEMA 4D
estimates how long it will take to refresh the viewports. If the estimated time exceeds the redraw time
limit specied here, a faster display mode will be used automatically. For example, Quick Shading will
be reduced to Wireframe. Or, if the wireframe mode is still too slow, Box will be used instead.
The default value is 600 milliseconds. To prevent a less detailed display mode from being used, set
Redraw Limit to a very high value such as 10000 milliseconds.
Editor : Pixel
These values specify the ratio of a pixel’s on-screen width to its on-screen height. The pixel ratio for
most monitors is 1:1. However, some display media use a pixel ratio other than 1:1. This will lead to
distortion unless the pixel ratio is adjusted accordingly. For example, circles will appear to be ellipses.
To calculate the pixel ratio manually, expand the editor window to ll the entire screen. Select the
side view and create a cube. Measure the width and height of the cube with a ruler and enter these
values into the corresponding boxes.
OpenGL Shading
Refresh
Smart Window Refresh
Some OpenGL cards do not support Smart Window Refresh and will display
errors if this option is enabled.
When enabled, this option accelerates window refresh under OpenGL if, for example, you move an
undocked manager over the viewports. If the option is disabled, OpenGL must refresh the entire
screen each time.
